This block is a commonly used block; it is used whenever the Stage must switch to a specific backdrop (instead of the Next Backdrop block, which does not always give the same backdrop). A variable (or any reporter) containing a number or the name of a backdrop can be dropped in.

History

Prior to Scratch 2.0, this block was called Switch to Background () and didn't fire an event upon running. During 2.0 development, this block was also called Switch to Scene (), then Switch to Backdrop (), before being finalized on Switch Backdrop to ().

It can also be replicated with a sprite that stamps the new background.

Example Uses

Because of its simplicity, this block does not have a specific list of main uses — it is simply used to change the background of the Stage. It can be used in animations, games, simulations — anything that requires changes between backgrounds.

Some common uses are as follows:

Starting a level

switch backdrop to [level1 v]

when backdrop switches to [level1 v] //in a sprite
go to x:(0) y:(0)

A game over message

switch backdrop to [game over v]

when backdrop switches to [game over v]
hide

Simply changing backdrops

switch backdrop to [scene2 v]

The Switch to Backdrop () block can be used in many ways; its simplicity is all.
